I am in the process of developing an application with around 30 to 40 features. Which is better in terms of performance, multi-page or multi-tab? In the following discussion, it is concluded that multi-page is a safer option, but is this still the case now?
This is a tough question without knowing the exact details about your app. One thing that changed since the last post is introduction of Dash Pages which really simplified creation of multipage apps:
From my personal experience I would go with multipage apps. This architecture is similiar to another web architectures. Problem of the “performance” as you are framing is more tight to precomoutation and caching in your app and not so much to the way you serve them.
